 Title:
THREE DIMENSIONAL FLOW SIMULATIONS FOR TYPICAL LAUNCH VEHICLES AT ANGLE OF ATTACK
 
Summary :
SUPERSONIC FLOW SIMULATIONS OVER TYPICAL LAUNCH VEHICLE CONFIGURATIONS ARE PRESENTED. TWO DIFFERENT COMPUTATIONAL CODES WERE USED IN THIS INVESTIGATION. BOTH ARE 3-D FINITE DIFFERENCE CODES WRITTEN FOR GENERAL, BODY-CONFORMING, CURVILINEAR COORDINATE SYSTEMS. THE FIRST CODE SOLVES THE EULER EQUATIONS WHEREAS THE OTHER CODE SOLVES THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS USING A MODIFIED BALDWIN-LOMAX TURBULENCE MODEL. SIMULATIONS ARE PERFORMED BOTH FOR THE VLS AND THE SONDA III-A CONFIGURATIONS AT ANGLE OF ATTACK AND FOR VARIOUS SUPERSONIC FREESTREAM MACH NUMBERS. COMPUTATIONAL RESULTS ARE VALIDATED WITH CODE-TO-EXPERIMENT AND CODE-TO-CODE COMPARISONS. KEYWORDS: LAUNCH VEHICLE, CFD, THREE-DIMENSIONAL FLOW, FLOW AT ANGLE OF ATTACK, SUPERSONIC FLOW.
